IMPROVEMENT IN STEREOSCOPES.

Speciiication forming part of Letters PatentNo. 190,160, dated May 1,1877; application filed February 27, 1877.

To all whom Vfit may concern;

13e it known that I, MATTHIAS J. RICE,'of

' Boston, in the county of Sui'olk and State of Massachusetts, haveinvented a new and useful Improvementin Stereoscopes; and do here- -bydeclare the same to be described in the following specication, andrepresented in the accompanying drawings, of which- Figure l is a sideview of a stereoscope provided with my invention. Fig. 2 is alongitudinal section of the handle and parts connecting such and thebody of the instrument l the projection of the arm of the stand hinge.

Such enables the handle to be used not only to manipulate theinstrument; when employed with the stand, and to aid in fixing itthereto, but to support it when out of engagement therewith.

In the drawings, A denotes a stereoscope, and B a stand therefor.

To the under side oi the bottom bar a of the stereoscope there is fixeda socket'piece, C, having a passage or socket, b, made diametri callyinto or through it to receive the projection c cfa bent arm, D, hingedto the top of the stand, such top and arm being provided with aclamp-screw, e, and nut f for holding the arm in position.

The projection c on being inserted within the passage or socket b, maybe secured therein by the screw d projecting from the handle E andscrewed against the projection and into a female screw, g, formed in thesocket-piece, as shown.

From the above it will be seen that by revolving the handle the screwmay be caused to hold the arm in the socket-piece. The handle is thusmade to serve the threefold purpose of operating the screw for clampingthe stereoscope to or unclamping it from its stand, or for aiding inmoving or inclining the stereoscope more or less, when clamped to thestand,

and for supporting it by the hand of the user when it, the saidstereoscope, may be out .of engagement with its stand.

l do not claim in a stereoscope the stand joint-piece, provided with astud and a pertorated arm, to be applied to plate having a recess toreceive the stud, and also having a female screw to receive a male screwprojecting from a handle, and going through the perforation of the arm.

I have the hinge part D without any.stud, but simply with a tenon, c,for use with the piece G, mortised or socketed to receive the tenon andit to it, and also having a female screw to receive the screw d of thehandle, which screw does not go through the tenen,

.but simply bears against it, such being advantageous, as it does away.with all necessity ot' separating the handle from the stereoscopeinorder to enable the latter to be separated from the stand.

I claimv l. In combination with the stereoscope A and its handle E, thescrew d (projected from the latter,) and the piece C, lixeil to theinstrument and provided with a socket, b, to receive the projection c ofthe hinge-arm D, and With a female screw to receive the screw d extendedfrom the handle.

2. The arm D, hingedto the stand B, and provided with the tenen c, inconnection or for use with the piece U, provided with the tenonsocket b,having the screw d ot' the handle E applied to it, as set forth.
